Which age group has a normal respiratory rate of 20-25 breaths per minute?

The normal respiratory rate for the age group of 3 to 7 years is indeed between 20 to 25 breaths per minute. This value reflects the physiological characteristics of children in this age range, where their metabolic needs are higher than those of adults, resulting in a quicker breathing rate to facilitate adequate oxygen exchange and carbon dioxide removal.

As children grow, their respiratory rates gradually decrease, reaching the adult level, which typically ranges from 12 to 20 breaths per minute. Infants have a significantly higher respiratory rate, often exceeding 30 breaths per minute, due to their smaller lung capacity and higher metabolic demands. The respiratory rates for older children, such as those aged 8 to 11 years, also begin to stabilize, moving closer to adult values. Understanding these age-related differences is essential for accurate health assessments and providing appropriate care.
